Full & Partial Rewiresin Stevenage & Hertfordshire

Modern rewires use twin-and-earth PVC-insulated cable (or low-smoke alternatives where required) sized correctly for each circuit's load, new consumer unit with RCD/RCBO protection, and current sockets, switches and light fittings. Cable sizing matters: undersized cable on a heavily loaded circuit like a cooker or shower can overheat even if everything else is installed correctly.

Containment, conduit, trunking or clipped cable routes, is chosen to suit the building construction, whether that's a solid-wall period property or a modern timber-frame extension.

Rewires happen in two stages. First fix is running the new cabling through the property before walls and ceilings are closed up; this is the most disruptive stage, as floorboards may need lifting and chases cut into walls for cable routes. Second fix comes after plastering, and involves fitting sockets, switches, light fittings and the consumer unit, then connecting and testing everything.

On occupied properties we sequence the work to keep at least some rooms usable at any time, rather than opening the whole house up at once.

A full rewire replaces the wiring and accessories throughout the entire property, usually alongside a new consumer unit: appropriate when wiring is old and deteriorating throughout. A partial rewire targets a defined area: an extension, a kitchen or bathroom being renovated, a loft conversion, or specific circuits identified as faulty. Partial rewires need careful planning to integrate the new circuits safely with what's being kept.

We'll always recommend based on condition, not just assume a full rewire is needed if a partial one genuinely covers the problem.

Common triggers include buying a period property with original wiring, extending or converting a loft, renovating a kitchen or bathroom, or an EICR flagging multiple serious defects. New-build and major refurbishment projects also need first and second fix electrics from scratch, which follows the same process as a rewire.

Each situation changes the scope but not the standard: every circuit gets tested regardless of whether it's a whole house or a single extension.

Domestic rewires are usually single-phase and organised room by room around a household's daily life. Commercial rewires, shops, offices, small units, often need to be phased around trading hours or done out-of-hours to avoid shutting the business, and may involve three-phase supplies and more complex containment. We've handled both, from one-bed flats through to larger commercial fit-outs.
